To @ZZ whom t mctyrconcern:

Be it known that I, HERMAN HAHN, a citizen of the United States,residing at 126 Thnrlow Block, San Francisco, in the county of SanFrancisco and State of California, have invented certain new and usefulImprovements in Cash Registers and Indicators; and I do hereby declarethe following to be a full, clear, and exact description of saidinvention, such 1o as will enable others skilled in the art to which itmost nearly appertains to make, use, and practice the same.

This invention relates to improvements in cash registers and indicators.

In the drawings, Figure l is a front elevation of a device constructedin accordance with this in vention. Fig.2 is a plan view in section ofthe upper portion of the case, showing the indicating-ribbons by whichthe various zo selected numbers are displayed. Fig. 3 is a plan view ofthe entire operative mechanism, the containing-case and a selection-dialbeing shown in section. Fig. 4. is a detail view, in side elevation, ofthe money-drawer-releasing mechanism, the drawer being shown in sectionand broken and compressed in space. Fig. 5 is a detail View, in frontelevation, of the selection-dial, readjusting-ring, and, in section, themoneydrawer-releasing lever 3o in its relative position. Fig. 6 is avertical central section of the said dial and ring and of the disks andthe mountings of the same. Fig. 7 is a detail viewin plan and partlyinsection, showing the construction and arrangeg 5 ment of theselection-dial, the keys, the disks, and the readjusting-ring. Fig. 8 isa detail view of the disks and the double dogs for holding the disksyand in dotted lines the position of the perforations in the releasing-4o disk when theksame isl turned backward in operation. Fig. 9 is avertical central section of the parts shown in Fig. 8. Fig. l0 is adetail in plan of a portion of the operatingdisk and doubleretaining-dogs. Fig. l1 is a front elevation of the indicating-ribbonand a constant-registering mechanism. Fig. 12 is a detail View of themain shaft, showing the beveled gear for operating the ribbon and insection the units-disk and ratchet-re- 5o taining wheel of the register.Figs. 13 and 14 are front` elevations of the register-disks of the tensand units, respectively, of the register on the ,dollar7 side of themachine. Fig. l5 is a similar view of the register-disk `of the units onthe cents side of the machine.

The objects which the present invention has in view are to produce amechanism of the nature indicated which is simple and accurate and rapidin operation and to reset all 6o ofthe indicating parts in their initialpositions between successive operations.

With these objects in view the invention consists in providing twoduplicate indicating and registering mechanisms in the same case, 6 5similar in all essential features, thel one to indicate and register thecents and the other the dollars of the purchase price and in operatingeach of these indicators and registers by spring-actuated mechanismsreleased by 7o and controlled by keys bearing numbers on their faces inthe serial order of their arrangement and by subsequently resetting thekeys and the indicating mechanisms to their original positions by themechanism by which the money-drawer is' operated. The two mechanismsbeing thus similar, I will in the description describe only one, thesame distinguishing numbers beingshown in the drawings as assigned toeach set of parts. 8o

The indicator to which the purchasers attention is called is formed by adouble ribbon 1, which is mounted on the drums or spools 2 2, the lowerof which is fixed on a shaft, on'the inner end of which is mounted 85the beveled gear 3. This beveled gear 3 and the shaftand spool to whichit is attached are rotated by a large gear 4, mounted on the end of amain shaft 5. The gears 3 and L.tare so calculated as to rotate thesmaller gear a 9o sufficient number of times to cause the ribbon l totravel its entire length driving one complete revolution of the gear 4and the shaft 5. The ribbon 'is provided withV two IOO read indescending on the other side of the said spool at the opening 7 in theback of the ease.

The shaft 5 is rotated in a forward direction by the coil-spring 3 andcarries near the forward end the operating-disk 9, by which its forwardmovement is controlled or arrested by the lng 10 on the edge thereofcoming in contact with one of the push-pins 11, said push-pins formingkeys and arresting devices which have been forced forward in the path ofthe said lug, (see Fig. 6 of the drawings,) said lug thus becoming aprojection fixed to the shaft to move positively therewith and eX-tending radially therefrom. These keys 11 are set about the dial 12 inequal divisions, which correspond with the divisions on the ribbon 1. Bythus controlling the rotation of the disk 9, shaft 5, and gear 4 theyalso control the travelof the ribbon 1. By assigning numbers to thesuccessive keys corresponding to the successive numbers on the ribbonthe number on the ribbon exposed before the openings 6 and 7 willcorrespond to the numberof thekey which has been pushed into the path ofthe lug` 10 to arrest it.

Between each operation it is needful that the shaft 5 and its connectedparts, including the disk 9 and ribbon l, be returned to the initial orzero point, and it is also needful that they be heldin such :initialposition, and that the key or pin 11 which was forward be returned backout of the path of the lug 10. It is for this purpose that the drum 13is mounted on the shaft 5 to wind the chain 14 on itself as the shaft isrotated. One end of said chain is connected to the drum, While its otherend passes over the idlers 15 15 and hangs downward through the loop 16on the lever 17 and is provided with the block 1S at or near the freeend of the chain and at the lowest extremity of the throw of the leveror loop 1G when the same is depressed and when the disk 9 is in itsnormal or locked position. Vthen the disk 9 is advanced, howeverslightly, the chain is wound on the drum and the block 18 is raised inthe path of the loop 16, which in descending carries it downward andunwinds the chain 14 and rotates the drum 13 and shaft 5 backward toreset and lock the disk 9.

The disk 9 is locked by the double dogs 19 and 20, which are mounted onthe pivot 2l, s'et out from the bracket 22. Each dog falls over anL-shaped lug23, set out from the face of the disk 9 (see Fig. 8 of thedrawings) when the said disk is in its normal or set position and whenthe ribbons are indicating O or No sale. The dogs are thus doubled thatone may be constantly held by the releasing member, which throws themout of engagement with the lug 23, while the other is immediatelyreleased and falls in position to engage the said lug as the same isreturned or reset prior to the releasing member being moved to permitthe other dog to engage the lug.

The releasing member is tho disk 24, the outer edge of which is providedwith the same number of perforations 25 as there are pins or keys 1l andinto which the ends of the pins are adapted to enter when pushed inwardto the limit of their movement. This disk is loosely mounted on theshaft 5 and has an oscillatory movement of about one-sixteenth of aninch, being held in its forward position by the weak spring 26 forcingthe pin 27 against the rear side of the lug 10 on the disk 9, which isheld by the dogs 19 and 20.

The dogs 19 and 2O are thrown out of engagement with the lug 23 bythrowing the disk 24 backward, causing the cam-shoulder 28 to ride underthe pin 29, set out from the side of the dog 19, clear of the lug 23when the pin is at the top of the cam. In this movement outward from thelug 23 the two dogs act simultaneously, being controlled by the smallpin 30, which is extended through the lower extension of the dog 20 intothe path of the lower extension of the dog 19. Vhen, then, the dog 19 ismoved outward by the cam 28, the lower extension impinges on the pin 30and -moves simultaneously the dog 2O until both dogs are clear of thelug 23 and the disk 9 is permitted to rotate forward. The pin 30 is heldin its position extended through the dog 2O by the spring 3l. Mounted onthe side of the bracket 22 is a stationary cam 32 in the path of the pin39, which raises outward the pin as the same is carried toward and overit by the movement of the dogs. The end of the pin 39 is rounded, andwhen itis raised sufficiently it rides on an abutting surface of the dog19 by reason of the pressure of the spring on the dog 20, which causesthe dog to immediately fly forward into the path of the lug 23, ready toengage the same as it is returned. The stop 34 maintains the dog 2O inthe propel' position in the absence of the lug 23. The dog 19 remains inits outward position, however, until the disk 24 is moved forward tocarry the cam 28 forward and allow the pin 29 to fall in position andthe dog 19 to engage the lug 23. During this separation of the dogs thepin 30 has rested against the dog 19 and does not extend forward untilthe same is in engagement with the lug 23.

The disk 24 is thrown back, as described,

by the key-pins 11 entering the perforations 25. For this purpose theperforations 25 are placed out of alinement with the perforations in thedial 12 and disk 35, in which the keypins 11 are mounted. (See Fig. 7 ofthe drawings.) This disadjustment is the distance required to move thereleasing-disk 24 to place the cam 28 full under the pin 29 to throw thedogs 19 and 2O from the lug 2' The ends of the key-pins are coned, asshown, to enter the perforations and to force the perforations 25 intotrue alinement by entering them and forcing the disk 24 backward toallow it. As

stated, this action of the disk 24 releases the disk 9 from theengagement of the dogs 19 and 20 and permits the same to be rotated for-IOO IIO

IIS

Ward by the spring 8 until the lug 10 strikes upon and is arrested bythe key 11, which hasl been pushed inward to release the disk. It is nownecessary that the key-pin 11 remain in this position until the kdisk 9is reset; otherwise the said disk would continue to rotate. The key 11is thus held by the friction of the disk 24 and the spring 26, pullingon the same. By thense and construction of the dogs 19 and 20 the disk 9may be returned and locked in position by the dog 20 before the key 11is withdrawn and the disk 24 moved to allow the dog 19 to engage thedisk. The disk 9 is reset by the depression of the lever 17, as abovedescribed. from the perforations 25 by the same lever moving thereleasing-ring 36 and inserting thecam-shaped extensions 37 under thepins 38, with which the key-pins are provided. (See Figs. 5, 6, and 7ofthe drawings.) This forces the key-pins 11 outward out of engagementwith the perforations 25. As stated,

this is accomplished after the disk 9 has beenl reset and locked. Thisaction of the ring 36 is caused by the upward movement of the lever 17.In the downward movement of the lever it comes in contact with the freeend of Y the pawl 39 and moves the same out of its path. In its returnmovement, however, it catches under the pawl in its fixed position andby it throws the ring around on its bearing on the disk 35 to free thekeys 11, as described. When the lever 17 has passed upward out ofengagement with the pawl 39, the ring is returned to its normal positionby the spring 40, and the path of the pins 38 in the key-pins is againfree.

The keys 1l are provided with enlarged heads, on which are imprinted theusual numbers seriatm, as shown at Fig. 1 of the drawings. The keys areheld in upright or correct position by the small tongues 41, extendedinto the circle of the perforations of the disk 35. (See Fig. 5 of thedrawings.) To receive these small tongues the key-pins are channeledpart of their length.

The money-drawer of this machine is released by the lever 17, which isfulcrumed on a standard 42 and engages a latch 43, which is raised outof engagement with the drawer 44 when the forward end of the lever 17 isdepressed, by which action the registers are reset to 0. It thereforebecomesA necessary in operating this machine to make the indication andregister only after the drawer is opened to receive the cash indicatedand registered. The lever 17 is raised to its normal position by thespring 45.

In the operation of a machine constructed in accordance with thisdescription and drawings accompanying the actions are as follows: Thefirst step is to open the drawer 44, which is done by depressing theforward end of the lever 17. The purchase-price is then pointed out onthe keys 1l, using both sets of dials to indicate the dollars and thecents of the purchase price. By pressing the correct ,sie

The key-pins 1l are extracted keys the indication is made by the ribbon1 traveling and coming to rest to expose the numbers on its surfacebefore the openings 6 and 7 corresponding with the numbers on the keyspressed inward. The drawer is closed after depositing the money ormaking change. The indicator continues to be eX- posed untilthe nextoperation. If the operation is to make change, this may be done bydepressing the lever 17 to open the drawer and by not using the keys,whereby the indication of the former sale will be destroyed and no newindication will be made. As each indication is made a constant register46, on and operated by each shaft 5, adds to the total amount of sales.The register used by me is shown and described in a patent issued toJoseph W. Whitney the 13th dayof June, 1899, and numbered 627,032, towhich reference is here made for a full explanation of its lconstruction and'operation.

Havingv thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
